Abstract: The monetary valuation of the radiological detriment is the cornerstone of optimisation of radiation protection. This concept first appeared in ICRP Publication 22 [1], in connection with the cost–benefit analysis model proposed by the Commission to select protection options allowing to maintain exposures ‘as low as reasonably achievable’. The key feature of this model is to look for the minimum total cost, i.e. the cost of protection plus the cost of the detriment defined as the monetary value of the potential health impact associated with the level of residual exposure. In its Publication 37, ICRP emphasised the need to take into account also the ‘subjective’ aspects of health detriment such as the perception of risk by individuals, as well as risk transfers between various groups of population (public, workers, present and future generations) [2]. Finally, in its last Recommendations, ICRP put more emphasis on the equity in the distribution of individual doses [3]. The aim of this paper is to present a model for the determination of the monetary values of the man-sievert reflecting the various objectives recommended by ICRP for the implementation of optimisation.

TL;DR: Research showed that prescriptions and practices for stakeholder engagement would benefit from acknowledging the normative and substantive rationales for engagement, and the need for developing radiological protection culture in a participatory, multi-disciplinary way is substantiated.

TL;DR: It is argued that stakeholder engagement in the field of nuclear and radiological emergency preparedness, response, and recovery (EPR & R) could be broadened in terms of stakeholders and forms of engagement, and strengthened in Terms of sustainability and impact.

TL;DR: The article summarizes the discussions and conclusions of these two workshops, in which the search for reasonableness was examined in three sectors: nuclear industry, medical practices and existing exposure situations, and it emerges that the implementation of the optimisation principle implies a clear identification of the challenges to be met in order to achieve the best protection in the prevailing circumstances.
